Study the following graph carefully and answer questions given below it.
Percent Profit = $$\frac{Income-Expenditure}{Expenditure}*100$$
If the incomes of Company B in 2002 and 2003 were in the ratio of 3 : 4 respectively. What was the respective ratio of expenditures of that company in these two years ?
Let the incomes in 2002 and 2003 be 3x and 4x respectively and expenditures be E1 and E2.
In 2002, % profit = 100 * (I-E)/E
=> .45 = (3x - E1)/E1
So, 3x= 1.45E1
In 2003,% profit = 100 * (I-E)/E
=> .5 = (4x - E2)/E2
4x = 1.5 E2
So, E1: E2 = 3/1.45: 4/1.5 = 4.5 : 5.8
